The talented folks at Signal Snowboards are back with one of their most practical creations yet. Using a sheet of ultra-thin solar cells from a company called Powerfilm Solar, they created a board that harnesses the sun's rays and turns them into usable electricity for charging a small device.

Because the solar cells are actually more flexible than your typical snowboard, the company's latest creation doesn't feel any different when tearing down the slopes. And it's particularly eco-friendly because when the board's riding days are over, it can easily be mounted on a roof where it will keep on soaking up the sun and powering your gear.
